This invention relates to a method of making a coil of wire and is adivision of my copending application, Serial No. 166,944, led .Tune 8,1950, now Patent No. 2,695,142, dated November 23, 1954. In making upcoils of Wire it is desired to cover the coil with paper lor cardboardand in the past it has been difficult to do this with the methods incommon use.

It is therefore an object of our invention to provide a method of makinga paper covered coil of wire.

This and other objqects will be more apparent after referring to thefollowing speciication and attached drawings, in which:

Figure 1 is a sectional view taken on the line l-l of Figure 2;

Figure 2 is an end view of Figure 1 taken in the direction of arrow II;

Figure 3 is a sectional view taken on the line III-lll -of Figure l;

Figure 4 is an end view of Figure l taken in the direction of arrow IV;

Figure 5 is an enlarged sectional view taken on the line V-V of Figure2;

Figure 6 shows a paper or cardboard disc used in carrying out ourinvention; and

Figure 7 is a sectional view of a completed coil of wlre.

Referring more particularly to the drawings the reference numeral 2indicates a hollow shaft which is adapted to be mounted on the arbor 4of a stranding machine. Welded to the shaft 2 is an outwardly extendingiiange or plate 6. A circular plate 8 is welded to the extreme end ofthe shaft 2 adjacent the plate 6. The plates 6 and 8 are connected by atubular member 10 welded to both plates. Radial reinforcing ribs 12extend from the outer periphery of plate 6 to the tubular member 10.Radial slots 14 are provided in the plate 6 for a purpose which willappear later. A slot 16 is cut in the plate 6 between each pair ofradial slots 14. Welded to the plate 6 on each side of slot 16 is a lug18. Aligned openings 20 are provided in each pair of lugs 18 forreceiving a pivot pin 22. Each of the pivot pins supports a barrelsegment 24. As shown, four barrel segments are provided with a spacetherebetween aligned with the radial slots 14. An axial slot 26 isprovided in at least two of the barrel segments 24. One end of a spring27 is attached to each of the barrel segments 24 with the other endbeing attached to the shaft 2. A circular plate 28 is welded to theshaft 2 a short distance from the end remote from plate 8. Gusset plates30 welded to the shaft 2 and plate 2S may be provided for reinforcement.Two studs 34 are welded to the plate 28 with the threaded end thereofextending outwardly for a purpose which will appear later. A cover plate36 is made up of an outwardly extending flange or plate 38 welded to atubular hub 40 which has an internal diameter just slightly greater thanthe outside diameter of the shaft 2. A ring 42 having a bevelled outersurface 44 is welded to the inner side ICC of plate 38. Plate 38 has aplurality of openings 46. therethrough for receiving the studs 34. Eachof the openings 46 has a portion 48 having a width slightly greater thanthe diameter of the studs 34 and a larger circular portion 50. Thediameter of the portion 50 is such that washer 52 and nut 54 which arefastened to each of the studs 34 can pass therethrough.

As best shown in Figure 5, each of the flanges 6 and 38 has a ring 56fastened to its youter periphery. An inwardly extending radial flange 58is attached to each of the rings 56 on the side of the flange 6 or 38adjacent each other. A space 60 is provided between the ange 5S and theflange 6 or 38.

The method of making a coil of wire is as follows:

The shaft 2 is slipped over the arbor 4 and is held in place thereon inany suitable manner. A cylindrical core C, preferably made of paper, isslipped over the barrel segments 24 and a side disc D is placed againstthe inner face of the flange 6. As best shown in Figure 6, the disc Dhas slots 60 in its inner periphery and slots 62 in its outer periphery.Prior to placing the disc D against the ange 6, the disc is bentinwardly over the core member C. A snap ring 64 is forced into theopening 60 with one side bearing against the flange 58 and the otherside bearing against the disc D to hold it in place. In like manner asecond disc D is positioned against flange 38. The cover plate 36 isthen placed against the flange 28 with the large portion 50 of theopenings 46 being aligned with the studs 34. The beveled portion 44 ofthe ring 42 bearing against similar bevel portions on the barrelsegments 24 force the barrel segments to their expanded position againstthe pressure of springs 27. The cover plate is then turned until thestuds 34 are in the narrow sections 48 of the openings 46. The nuts 54are then tightened to hold the reel in assembled position. The end ofthe wire W being coiled is forced through the core member C into one ofthe openings 26 in the barrel segments 24 and reeling is begun. When thewire coil has been built up to a diameter substantially equal to thediameter of the disc at the base of the slot 62, the wire is cut and theends of the disc D are bent over the outer periphery of the coil. Ifdesired, the paper covering 66 may be placed around the outer peripheryof the coil. Steel strapping 68 is then wrapped around the inner surfaceof the core between the barrel segments, outwardly around the sides ofthe coil in the slots 14 and around the outer periphery of the coil andthe ends fastened together. The wrapping of the coil may be done eitherwith the reel mounted on the arbor 4 or with the reel removed therefrom.

While one embodiment of our invention has been shown and described itwill be apparent that other adaptations and modifications may be madewithout departing from the scope of the following claim.

We claim:

The method of making a coil of wire which comprises placing acylindrical core on a collapsible barrel having a plurality of segments,providing a pair of side discs having slotted outer portions and slottedinner portions, bending the slotted inner portions at right angles tothe plane of the discs, placing one of said side discs against a sideange with its bent inner slotted portion extending inwardly over thecylindrical core, applying a removable side flange with a beveledportion contacting the barrel segments to support and expand the same,placing the other of said side discs against the removable side flangewith its bent inner slotted portion extending inwardly over thecylindrical core, coiling wire on said core between said side discs,bending the outer slotted portions of said side discs over the outerperiphery of the coiled wire, wrapping strapping around the innersurface of said core outwardly around the said side discs and around theouter periphery of said coil, then removing the removable side ilangewith its beveled portion to collapse Y Athe barrel and removing thecompleted coil therefrom. 5
